 ## General Information

 Qt 4.7 as a javascript engine called QScriptEngine that is well integrated with Qt. QScriptEngine allows an easy interface with C++ objects and offers great flexibility. Using javascript, we can then interact with the variables on the CAN bus. Function generators, variable conversions and complex logic can then be implemented in javascript for testing before the complete implementation in the embedded microcontroller. Test scripts can also be created to interact with multiple modules at once. The complete documentation of the QScriptEngine is available on the [Qt/Nokia web site](http://doc.qt.nokia.com/4.6/qscriptengine.html).
